As of Friday 1st February good progress has been made on the J72's winter maintenance and re-tube. Most of the mechanical work is complete. Adam Dalglesh, with help from NELPG volunteers, has installed all of the new tubes into the boiler. All the tubes at the firebox end are expanded and some of them have been beaded over. At the smoke box end some of the tubes are expanded. The re tube is expected to be complete this week.
